Problems solved by technology

[0003] A disadvantage of this yarn guide according to the prior art has been found to be that the hollow guide element made of ceramics, which is directly connected to the arm of the yarn guide, itself does not wear significantly under the impact of the yarn, but due to the The breaking elongation (Bruchdehnung) of the guide element is small, so that the bending moments that occur when laying the yarn at high frequencies can easily break the guide element, or in the case of guide elements with additional rods inside the guide element, At least the guide element will peel off the bars

Embodiment Construction

[0020] figure 1 is a schematic diagram of a yarn guide 1 according to the invention. The yarn guide 1 is finger-shaped or pointer-shaped and has a shape that tapers towards its free end. The wider end of the yarn guide 1 is connected to a separate motor drive 3 about the longitudinal axis of which the yarn guide 1 can pivot. In order to lay the yarn on a rotating bobbin 4, which in the shown embodiment is driven by a drive roller 2, the yarn guide 1 is driven along the bobbin by an independent motor drive 3 of the yarn guide 1. Width traverse.

[0021] The arm 5 of the yarn guide 1 has on its narrower free end two guide elements 6, 7 made of ceramics, which are configured as cylindrical hollow bodies, such as figure 2 As shown, both guide elements 6 , 7 are fastened to the arm 5 via elastically bendable rods 8 , 9 in a form-fit and / or force-fit manner. The guide elements 6 , 7 are arranged axially at a distance from the arm 5 via elastically bendable rods 8 , 9 . The ela...

Abstract

The invention relates to a thread guide (1) having a finger or needle shaped arm (5), where one end of needle shaped arm (5) is connected with a drive device (3). The free end of the needle shaped arm (5) has guiding elements (6, 7) that are formed as hollow body made of ceramic for threading a thread on a rotating coil (4) that is parallel to coil axis. The guide elements (6, 7) are connected with free end of the arm (5) by flexible elastic rods (8, 9).

Description

technical field [0001] The invention relates to a yarn guide comprising a finger-shaped or pointer-shaped arm, which is connected at one end to a drive and has a hollow body made of ceramics at its free end. Two guide elements for laying the yarn on the rotating bobbin parallel to the bobbin axis. Background technique [0002] WO 2007065583 A1 already discloses a yarn guide of the aforementioned type. The thread guide described there has at its free end two guide elements made of ceramic, which are formed as cylindrical hollow bodies and which are arranged directly on the arm in a form-fit and / or non-positive manner. These two guide elements form a yarn guide within which the yarn is guided onto the bobbin for laying the yarn. Guide elements made of ceramics are used to counteract the abrasive effects of high-speed yarn laying on the guide elements. [0003] A disadvantage of this yarn guide according to the prior art has been found to be that the hollow guide element mad...
